First, I'm able to get my T1 weapon today. Do I go Staff or one hand and off hand?

Second, I've been thinking about splitting to Frost for Arenas, and Fire for BGs. Is the Fire thing dumb? If I do that, I'll need another set of gear, I have a pretty decent PVE gear set, does PVE gear do okay in BGs? Or should I just start another set for Fire if I should even bother being fire to begin with.

Third, does anyone use a Macro that cast Cold Snap and Ice Barrier at the same time? Is this worth it or should I keep them seperate?

1) one-hand, off hand.
2) i'm pretty biased because i HATE fire and think the entire spec is stupid so i'm sure you can deduct my answer. pve gear isn't worth it at all anymore because of pvp power so stick to full pvp.
3) i'd be pretty surprised, whatever suits you man. my advice would be to have seperate binds.
